ONTARIO OPERATIONS AUDIT Executive Summary Golder Associates Ltd.’s (Golder) Competent Persons, Greg Greenough, P.Geo., and Kevin Beauchamp, P.Eng., have visited the Vale Ontario Operations Project from July 5 to 9, 2010 and validated that part of the mineral resource that is the basis for the following Mineral Reserve estimate as at June 30, 2010 for the Ontario Operations. During the site visit they inspected mining operations, interviewed personnel and gathered information required to evaluate the appropriateness of the data and methodology used to estimate the resources and reserves. A list of people contacted for this study includes: Steve Lowen – Principal MRMR Geological Engineer Lee Weitzel – Manager – Business Planning Chris Davis – Manager – Mines Geology Trevor Courchesne – Chief Engineer - Business Planning Coleman, Creighton and Totten Mines Tom Corkal – Chief Engineer - Business Planning North, Stobie and Garson Mines Richard Jundis – Senior Mine Engineer Scott Jeffrey – Chief Geologist – Design and Evaluation This study includes a review of technical reports, memoranda and supporting technical information obtained from Vale. Reports on previous internal and external technical reviews and audits were also made available to Golder (e.g., an independent audit of Garson Deep by SRK Consulting carried out in August, 2009). The mineral reserve estimates provided to Golder were expected to conform to the requirements of the Securities Exchange Commission’s Industry Guide 7 and to Canadian National Instrument (NI) 43-101 using specific terminology from CIM (2004). No exceptions were found to these requirements. The mineral reserve statement at June 30, 2010 for the Vale was audited by Golder. The mineral reserve audited by Golder was based on the mineral resource models and was prepared using costs, optimisation, mine design and scheduling practices that are appropriate. Golder accepts the procedure adopted to convert the mineral resource into a mineral reserve. The numbers are appropriate for the purpose of public reporting in that they provide an acceptable prediction of the available mineral reserves. The tonnes and grades are reported at an appropriate economic cut-off grade based on documented costs and prices. The following table with the mineral reserve figures are provided at the appropriate level of precision for public reporting.

Ongoing labour relations may result in lower than expected performance of baseline business. The resource block modelling methods and factors for mining recovery and dilution employed at the Ontario Operations are completed to accepted industry standards and appropriate for mineral reserve reporting. Geotechnical issues are likely to persist at the mines in the Ontario Operations. Furthermore, orebodies at greater depth have an increased likelihood of issues with regard to mining recovery, productivity and mining costs. However, it is the opinion of the QP that the ground control programs at the Ontario Operations have an established track record in addressing these geotechnical issues. The Ontario Operations is required to meet proposed government regulations on sulphur dioxide emissions reduction. Economically and technically feasible solutions for reducing emissions will be required to prevent closure of the smelter and refinery, or a significant reduction in plant throughput.

    'fnp AtvrERrcAN MrxERALocrsr JOURNAL OF THE MINERALOGICAL SOCIETY OF AMERICA Vor,. 8 JUNE, 1923 No.5 MINERALOGRAPHY AS AN AID TO MILLING1 Brrrs TsousoN,University of Toronto The accurate determination of the opaque minerals present in an ore is very often of prime importance to the mill-man if he would work out the problem of separation intelligently. It is sufficiently obvious that a chemical analysis or an assay will only give him data as to the elements present and will leave him more or lessin the dark as to the minerals representedin the ore. Since it has been found that certain sulfidesare more amenable to flota- tion methods than others, the value of accurate mineralogical determination of the ores would appear to be particularly necessary 'in this form of milling. However, it should also be quite evident that any milling problem would be benefited at its inception by a careful study of the mineral content of the ore, the approximate quantitative proportions of the minerals present, and their mutual inter-relationships. As far as the writer is aware the only satisfactory method for examining these ores microscopically is by means of , polished sections in reflected light. This branch of Mineralogy, known variously as Mineralography or Mineragraphy, may also be applied to the microscopic study of mill-products in the difierent stages of separation. Where the fragmental ma-terial is fairly coarse a thin layer of it may be set in melted sealing-wax and polished in the ordinary way. If the material is fine enough to pass through a 4S-meshscreen, before polishing, it must be mixed with a combination of melted sealing-wax and balsam.

Group – subsidiaries Effect of changes in the structure of the KGHM Polska Miedź S.A. Group during the reporting period Purchase of KGHM INTERNATIONAL LTD. (formerly Quadra FNX Mining Ltd.) On 5 March 2012, the KGHM Polska Miedź S.A. Group purchased from the former shareholders of Quadra FNX Mining Ltd. with its registered head office in Vancouver (“Quadra FNX”) 100% of the shares of Quadra FNX. The consideration transferred comprises: the purchase of ordinary shares for the amount of PLN 9 363 million, the purchase of warrants for the amount of PLN 39 million, the realisation of purchased warrants in the amount of PLN 305 million. The shares were purchased in execution of the agreement dated 6 December 2011 signed by the Parent Entity of the KGHM Polska Miedź S.A. Group and Quadra FNX under a Plan of Arrangement recommended by the Board of Directors of Quadra FNX (“Agreement”). The shares purchased represent 100% of the share capital of Quadra FNX and 100% of the votes at the General Meeting of this company. 5 March 2012 was assumed as the date of obtaining control. Until the moment of obtaining control by the KGHM Polska Miedź S.A. Group, the Quadra FNX shares were listed on the TSX Venture Exchange in Toronto. The operations of Quadra FNX (name changed to KGHM INTERNATIONAL LTD. from 12 March 2012) are focused on mine production of metals (including copper, nickel, gold, platinum, palladium) in the following mines: Robinson and Carlota in the USA, Franke in Chile, and McCreedy West, Levack (with the Morrison deposit) and Podolsky in Canada.

  • Myths of Deep and High Stress Mining — Reality Checks with Case Histories
    Deep Mining 2017: Eighth International Conference on Deep and High Stress Mining – J Wesseloo (ed.) © 2017 Australian Centre for Geomechanics, Perth, ISBN 978-0-9924810-6-3 doi:10.36487/ACG_rep/1704_58_Suorineni Myths of deep and high stress mining — reality checks with case histories FT Suorineni University of New South Wales, Australia Abstract The theme of this conference is ‘deep and high stress mining’. Obviously, mining at depth and in high stress is a current challenge and will continue to be so. Despite the several years of dedication to this subject and its importance, the definition of what is ‘deep’ and ‘high stress’ remains a matter of conjecture. Clear understanding of these terms, are fundamental to the design of excavations to achieve the benefits of the knowledge accumulated on the subject over the years. This paper aims at critically examining conditions that constitute high stress and explores what is ‘depth’ in the mining context. International case histories are used to demonstrate how a misunderstanding of ‘depth’ and ‘high stress’ can result in wrong mine layouts and excavation designs. The paper then provides conditions that constitute high stress and deep mining as a guide to mine layouts and the design of excavations to cope with these conditions. Keywords: deep mining, high stress, case histories 1 Introduction Stress is a significant factor in determining the safe and economic extraction of orebodies and, hence, an important consideration in determining mining methods. Stacey and Wesseloo (1998) state that from the point of view of planning of mining operations, the in situ stress field is the most important input parameter for modelling of excavations.
